SMASH-PROTECTOR.

Specification of Letters Patent.

Original application filed. July 24, 1908, Serial No. 445,155. Divided and this appIication filed August 14,

1909. Serial No. 512,785.

To all whom may concern:

Be it known that I, LOUIS H. LANDRY, a citizen of the United States, residing at Uxbridge, in the county of lVorcester and State of Massachusetts, have invented a new and useful Smash-Protector, of which the following is a specification.

This invention relates to a smash protector for looms and is a division of my Patent No. 943,028, granted Dec. 14, 1909, on a loom, the application for which was filed July 24th, 1908, Serial No. 44:5,155.

T he principal objects of this invention are to provide a simple construction capable of working without the complications usually thought necessary in this art for the purpose of indicating absolutely whenever the drop boxes start to change when a shuttle is not in proper position therein; to provide a box guide designed to prevent the shuttle from tripping, the bobbin from splitting; the shuttle from flying out, and the filling from cutting; and to provide means operated thereby whereby the loom will be stopped when such condition of adairs exists.

Another object of the invention is to provide for securing the above mentioned re sults by adding only a few parts to the ordinary loom construction.

Further objects and advantages of the in- 'ention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which liigure 1, is a front elevation of a portion of the front box guide of a loom showing one embodiment of this invention applied thereto; Fig. 2 is an end view of the same partly in section; Fig. 8 is a plan view thereof; and Fig. 1 is an elevation showing certain connections for stopping the loom.

The invention is shown applied to a loom having on the lathe 10 thereof, a shuttle box guide 11 for the shuttle box 12. From each end of the lathe a plate 13 extends upwardly provided with a slot 1 In order to stop the loom in case a shuttle is left part way in or part way out of the shuttle box as the latter rises, a feeler 15 is provided on the lathe above the path of the shuttle so that as the shuttle box rises, if a shuttle is under the feeler it will cause the feeler to swing on its pivot against a spring 16 and to turn a lever 17 passing through the slot 14:. The end of this lever operates through a system of levers 18 on a finger 19 to turn the shipper lever 20 and stop the loom. This stops the picking motions at both ends of the loom, and provides for operating the shipper lever automatically to stop the loom without interfering with the ordinary hand-operation of the shipper lever. The levers 18 are pivoted at 21 on the frame.

While I have illustrated and described a preferred embodiment of the invention, I am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction shown and described, but

What I do claim is:-

1. In a loom, the combination of a shuttle box, means for raising and lowering it, a feeler located adjacent to the inner end thereof in position to be engaged by a shuttle protruding from the box when the box is raised, said feeler consisting of a pivoted. plate, a spring for holding the plate down, a lever resting on the top of said plate and having a projection, and means cooperating with said projection for stopping the loom.

2. In a smash preventer for looms, the combination of a pivoted plate, means for holding it in position to be engaged and raised positively by the shuttle when protruding from the box as the box rises and adapted to drop When the shuttle is absent, and means connected with the plate for stopping the loom when the plate rises.

3. In a loom, the combination with a lathe, and a shuttle box guide thereon, of a feeler pivoted above the lathe, a spring for normally holding the feeler down to the level of a shuttle in the shuttle box, a shipper lever having a finger thereon, and a system of levers adapted to be operated by the feeler and engaging one side of the finger on said shipper lever for positively operat ing said shipper lever to stop the loom when the feeler moves in one direction.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
